You might recall my post from last week about QR codes. I wrote that don't think they should be used to enhance book content. I also wrote that I thought a better solution would come along. And now it has.
I just caught this demo video for Google Googles. I've read a couple of the reviews posted today, and it's exactly what I was thinking of. BTW, Google just updated their iOS app to include Googles (it's also available for Android). It's worth downloading, IMO.
Nate Hoffelder is the founder and editor of The Digital Reader:
"I've been into reading ebooks since forever, but I only got my first ereader in July 2007. Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums. It's a great community, and being a member is a joy. But I thought I could make something out of how I covered the news for MobileRead, so I started this blog."
